Well, here’s further proof that Google can and will slowly take over the world. The company has filed a patent for something everyone desperately needs: a neck tattoo that serves as a lie-detector.

Google’s Motorola Mobility division filed the application last year, and it was published on Thursday, the Register reports. To clarify: this isn’t a permanent tattoo. Like the password tattoo, which Motorola is also developing, the patent describes an electronic tattoo that adheres to a sticky substance on the skin. It contains an embedded microphone and hooks up to your mobile device, enabling wireless communication. That tattoo could have several functions, but the most intriguing is the lie-detection. The patent explains:

Optionally, the electronic skin tattoo 200 can further include a galvanic skin response detector to detect skin resistance of a user. It is contemplated that a user that may be nervous or engaging in speaking falsehoods may exhibit different galvanic skin response than a more confident, truth telling individual.
